Description

The Griswold Controls Automatic Flow Limiting Valve is used in many different applications, mostly in the HVAC industry to maintain balance in an HVAC System. The stainless steel flow limiting cartridge has a spring loaded cup that dynamically absorbs pressure fluctuations resulting from changing system conditions due to varying heating/cooling loads. These fluctuations in pressure, within a given pressure differential control range, do not change the flow through the valve, therefore the flow is controlled to within +/- 5% of the designed flow.
